What to do when sprites wont go in my game display whenever i drag and drop

i drag my sprites from the sprites folder and the are not a picture and whenever i try to drag it into the game display it does not work it shows the circle but the character or background does not work
ps this only happens with the sprites i download not the assests one which u download ingame

Try to put on 3d view to see if the sprite is rotated along a different axis.
